Debunking the MSG myth

I happened upon this article http://www.salon.com/food/feature/2010/03/17/msg_huffington_postrecently. I hadnt realized that MSG has been re-vilified. The article makes excellent points about how MSG has been exhaustively tested and repeatedly proven to be safe. Why is it people are still so scared of it? Glutamate and glutamic acid are ubiquitous in foods (soy, cheese, balsamic vinegar, beef, tomatoes, shrooms). Given that its "natural," what makes people think that adding MSG to foods is bad? That powder has a special place on my spice rack. And if you think about it, crystallizing MSG into a powder is scarcely different than how they make sugar. Thoughts?
